Abstract

L'invention concerne une grille de chantier d'avion disposée au-dessus du segment de la section centrale du fuselage servant à recevoir les supports principaux du train d'atterrissage en position repliée, laquelle comprend des barres transversales fixées à des entretoises du fuselage, et plusieurs barres longitudinales supportant les rails de grille de plancher. La grille de plancher sur ledit segment comprend des rails supplémentaires périphériques par rapport aux côtés longitudinaux de chaque entretoise. Les rails supplémentaires périphériques sont connectés entre eux par le biais de barres transversales en coupe ainsi qu'aux côtés opposés de chaque entretoise. Chacun des rails périphériques est connecté, par le biais d'un support vertical et d'une barre-pontet transversal au côté de l'entretoise et à la barre longitudinale la plus proche correspondants. Les sections d'extrémité des barres transversales en coupe sont connectées à une entretoise par le biais de charnières à trois degrés. Les sections intermédiaires de ces barres et les supports verticaux comprennent des charnières d'extrémité à un degré. Chacun des barres-pontets est connecté à l'entretoise par une charnière à trois degrés, et à la barre longitudinale la plus proche par une charnière à un degré capable de déplacement transversal en parallèle à l'axe transversal de l'avion.
